论文摘要
CEP的功能，我们观察到从调制到连续的SHHG频谱的过渡，表明从双重对比度到高对比度分离的Attosent脉冲发射的过渡。对于大多数驱动脉冲CEP，XUV光谱连续性的单次射击支持隔离度脉冲在10到50之间，隔离度在10至50之间，这代表了隔离度的差异显着提高，并且比在10 Hz处获得的2个周期驱动因素获得的先前结果相比，相对于先前的结果，这是显着的提高。 2D粒子中的模拟证实了这种解释，并预测了即使没有任何光谱过滤的孤立脉冲的产生百分比效率。
function of the CEP, we observe a transition from a modulated to a continuous SHHG spectrum, indicating the transition from double to high-contrast isolated attosecond pulse emission. Single shot-acquisitions of XUV spectral continua support isolated attosecond pulses with isolation degrees between 10 and 50 for the majority of the driving pulse CEPs, which represents a significant improvement in terms of isolation degree as well as repetition rate over previous results obtained with 2-cycle drivers at 10-Hz. 2D Particle-in-cell simulations corroborate this interpretation and predict percent-level efficiencies for the generation of an isolated attosecond pulse even without any spectral filtering.
